There’s a [variable\_dt option in game.project](https://www.defold.com/manuals/project-settings/#_display). If the value is unchecked the `dt` will always be 1/60, not matter how fast or slow your frames are. If the `variable_dt` is checked the `dt` value passed to update will reflect actual frame time and a frame that takes longer to complete will have a `dt` larger than 1/60.
